Gepple is one of the four scientists of Primus, and even though most of the time he's just as bickering and coward as his partners, there are times that he's more level-headed than the others. Gepple is the shortest scientist of the four. Gepple is the inventor of "Gepple's Goo".

Trivia (Clawful94): Gepple was voiced by Don Brown in the "New Adventures Of He-Man" cartoon series. As the series goes on, Gepple is seen less than he did in the begining.
